Shoulder Surgery

The shoulder is a complex joint. There are three bones and two joints that contribute to shoulder function– the humerus, clavicle, and scapula are the bones. The ball and socket joint of the shoulder is between the humerus and the scapula. The acromial clavicular joint between the scapula and clavicle moves with forward elevation of the arm and helps stabilize the shoulder on the chest wall. The shoulder is the most mobile joint in the body and because of this it is easily injured.
